Technical Field

[0001] The utility model generally relates to the technical field of container structures, and more specifically to a container. Background Art

[0002] As we all know, refrigerated containers regulate the temperature inside the container through the air circulation of the fan. Generally speaking, there are two situations, one is the upper air outlet and the lower air return, and the other is the lower air outlet and the upper air return. The specific air outlet method depends on the structure of the fan used.

The container 1 also includes an air inlet channel 30, an air inlet switching device 40 and a return air channel 50, the air inlet channel 30 has an upper air inlet 30a and a lower air inlet 30b, and the lower air inlet 30b is connected to the box body 10. The air inlet switching device 40 is movably arranged at the upper air inlet 30a between a first position and a second position. Specifically, the air inlet switching device located at the first position connects the fan air outlet 20a and the upper air inlet 30a, and the air inlet switching device 40 located at the second position closes the upper air inlet 30a. The return air channel 50 may be arranged on the side of the air inlet channel 30, and the return air channel has an upper return air inlet 50a higher than the fan return air inlet 20b and a lower return air inlet 50b lower than the fan return air inlet 20b. Furthermore, the container 1 may further include an upper baffle 52 and a lower baffle 53. The upper baffle 52 is movably disposed at the upper return air outlet 50a between the third position and the fourth position. The upper baffle 52 located at the third position connects the box body 10 and the upper return air outlet 50a, and the upper baffle 52 located at the fourth position closes the upper return air outlet 50a. Correspondingly, the lower baffle 53 is movably disposed at the lower return air outlet 50b between the fifth position and the sixth position. The lower baffle 53 located at the fifth position connects the box body 10 and the lower return air outlet 50b, and the lower baffle 53 located at the sixth position closes the lower return air outlet 50b.

[0059] According to the container 1 of the utility model, the opening and closing of the upper air inlet 30a is controlled by the air inlet switching device 40, and the opening and closing of the upper return air outlet 50a and the lower return air outlet 50b are controlled in cooperation with the upper baffle 52 and the lower baffle 53, so as to change the air circulation direction in the box and improve the transportation application range of the container 1.

[0060] Return to Reference Figure 1 The box body 10 may include a front end 11, a door end 12, a top plate 13, a bottom plate 14, and a side plate 15. It is understandable that the fan 20 may be installed at any position of the front end 11, the door end 12, and the side plate 15. For example Figure 1 In the embodiment, the fan 20 is installed at the front end 11 , and the fan 20 can partially extend to the inner side of the box body 10 .

[0061] See also Figure 3 , Figure 3 A wind circulation method with upper air intake and lower air return is shown. Figure 3 and Figure 4, the air inlet switching device 40 may include a housing 41 and a conversion member 42. The housing 41 is connected to the fan 20, and the conversion member 42 is movably connected to the housing 41 between a first position and a second position. Further, the conversion member 42 may include a wind shield 421, a partition 422, and a side connecting plate 423. The wind shield 421 may be expanded and retracted, and the wind shield 421 needs to be airtight, for example, the wind shield 421 is made of canvas. The partition 422 is pivotally connected to the housing 41, and the side connecting plate 423 is connected to both the wind shield 421 and the partition 422. For example Figure 3 and Figure 4 In the embodiment, the side connecting plate 423 is connected to both sides of the partition 422 along the width direction of the container 1, and the side connecting plate 423 is connected to an extensible end of the wind shield 421. It can be understood that the side connecting plate 423 is slidably connected to the shell 41. In the illustrated embodiment, the conversion member 42 may also include a sliding pin 424, which is connected to the side connecting plate 423, and the sliding pin 424 is located between the side connecting plate 423 and the shell 41. Accordingly, the shell 41 may be provided with a slide groove, and it can be understood that the slide groove is an arc shape along the cross section of the vertical container 1, and the end of the sliding pin 424 away from the side connecting plate 423 is connected to the slide groove. Further, the movement of the conversion member 42 requires power drive, for example, the conversion member 42 has an operating part protruding from the shell, and the staff drives the side connecting plate 423 to move through the operating part, and is equipped with necessary limiters so that the side connecting plate 423 can be fixed within the stroke. Accordingly, the conversion member 42 may also be connected to an external automated driving member, and the conversion member 42 may be driven to move by necessary electrical control. Accordingly, the movement of the upper baffle 52 and the lower baffle 53 may also be controlled manually or by an external automated driving member.

[0062] Please continue reading Figure 3 and Figure 4 The air inlet channel 30 may include an upper air duct 31 and a lower air duct 32, the upper air duct is located inside the box 10 and connected to the air inlet switching device 40, the lower air duct is located inside the box 10 and connected to the air inlet switching device 40, and the lower air duct 32 is located below the upper air duct 31. It can be understood that when the air inlet switching device 40 is in the first position, the upper air inlet 30a is connected to the upper air duct 31, and when the air inlet switching device 40 is in the second position, the upper air inlet 30a is separated from the upper air duct 31, and the lower air inlet 30b is always connected to the lower air duct 32. Figure 3In the embodiment, the upper air duct 31 is located at the top of the inner side of the box body 10 (i.e. connected to the bottom surface of the top plate 13), and the lower air duct 32 is connected to the fan 20 (located on the back of the front end 11). It can be understood that the lower air duct 32 is located below the upper air duct 31 and is arranged perpendicular to the upper air duct 31. In order to ensure that the airflow flows inside the entire box body 10, the free ends of the upper air duct 31 and the lower air duct 32 are spaced from the inner side of the box body 10 along their respective extension directions. At the same time, in order to ensure that the fan return air outlet 20b is unobstructed, as shown in FIG. Figure 3 In the embodiment, the fan return air outlet 20 b protrudes from the lower air duct 32 along the width direction of the container 1 .

[0063] Furthermore, the container 1 may further include a wall panel 51, which is located on the inner side of the box body 10 and connected to the downwind duct 32, and extends horizontally to the inner wall of the box body 10. Figure 3 In the embodiment, the wall plate 51 extends to the inner wall of the box body 10 along the width direction of the container 1. The upper baffle plate 52 is pivotally connected to the wall plate 51 or the box body 10, for example, it is pivotally connected to the wall plate 51. Correspondingly, the lower baffle plate 53 is pivotally connected to the wall plate 51 or the box body 10, for example, it is pivotally connected to the box body 10. In addition, in order to improve the sealing performance of the upper baffle plate 52 and the lower baffle plate 53, Figure 4 In the embodiment, the upper baffle plate 52 has a flange, which is connected to the side of the upper baffle plate 52 along the width direction of the container 1 to improve the fit with the inner wall of the box body 10.

[0064] See also Figures 1 to 4 , the following briefly describes the air circulation method of the upper air intake and lower air return of the container 1. The wind hood 421 is in a retracted state, and the partition 422 closes the lower air inlet 30b. The fan 20 is started to operate, and the fan 20 discharges air from the fan outlet 20a. The airflow reaches the upper air inlet 30a and flows into the upper air duct 31, and then the airflow flows to the inner side of the box body 10. Correspondingly, the upper baffle 52 is located in the fourth position to close the upper return air port 50a, and the lower baffle 53 is located in the fifth position, so that the box body 10 is connected with the lower return air port 50b, and the airflow flows into the fan return air port 20b through the lower return air port 50b to complete the cycle.

[0065] See also Figure 5 and Figure 6, the following briefly describes the wind circulation method of the container 1 with lower air intake and upper air return. At this time, the wind hood 421 is in the unfolded state, the partition 422 opens the lower air inlet 30b, and the upper air inlet 30a and the upper air duct 31 are separated by the unfolded wind hood 421. Correspondingly, the upper baffle 52 is located in the third position so that the box body 10 is connected with the upper return air port 50a, and the lower baffle 53 is located in the sixth position to close the lower return air port 50b. Start the fan 20 to operate, and the fan 20 discharges air from the fan outlet 20a. The airflow reaches the upper air inlet 30a and flows directly to the lower air inlet 30b, thereby entering the lower air duct 32. After that, the airflow flows inside the box body 10, and finally flows into the fan return air port 20b from the upper return air port 50a to complete the cycle.

[0066] It can be understood that in order to facilitate maintenance and replacement of the air inlet switching device 40 , the air inlet switching device 40 can be constructed to be detachably connected to the air inlet channel 30 .

[0067] According to the container 1 of the utility model, the air inlet switching device 40 controls the opening and closing of the upper air inlet 30a, and cooperates with the upper baffle 52 and the lower baffle 53 to control the opening and closing of the upper return air vent 50a and the lower return air vent 50b, so as to change the air circulation direction in the box and improve the transportation application range of the container 1. And each device can be flexibly arranged at different positions in the box body 10, so as to improve the practical flexibility. In addition, a manual or automatic driving member can be externally connected according to the use requirements to flexibly control the operation of each functional component such as the air inlet switching device 40, the upper baffle 52, and the lower baffle 53.
